Abstract
A data processing apparatus has a memory and a first storage apparatus and reads a data area from a second storage apparatus (a storage apparatus which is slower than the first storage apparatus and stores a plurality of data areas as data constituent elements). Regarding each processing block, the data processing apparatus determines whether an open/closed area for processing of a first processing block which is the processing block should be an entire area or a partial area of the data area, based on whether or not the data area which is input and/or output by the processing of the first processing block can also be accessed by processing of a second processing block which is a processing block other than the first processing block, and whether or not the second processing block is being executed.
